Questão 645671

\(1-\frac{1}{r^{k-1}}\\) / \(1-\frac{1}{r^{k-1}}\ \left[\frac{r_c^k-1}{k\left(r_{c^{-1}}\right)}\right]\)

\(1-\frac{1}{r^{k-1}}\left[\frac{r_c^k-1}{k\left(r-1\right)}\right]\) / \(1-\frac{1}{r^{k-1}}\)

\(1-r^{k-1}\) / \(1-\frac{1}{r^{k-1}}\)

\(1-\left[\frac{r_c^k-1}{k\left(r_c-1\right)}\right]\) / \(1-\frac{1}{r^{k-1}}\)
